To all whom it may concern:

1 Be it known that I, FREDERICK W. WILD,

7 Jr.', of the city of Baltimore and the State. of

Maryland, have invented certain Improvements in Labeling-Machines, ofwhich the 7 following is a specification.

This invention relates 1 rincipally to a peculiar construction of aabeling machine whereby certain parts of the same can be so "affixing oflabels towns of different diameters, as will hereinafter fully appear.

In the description of the said machine which follows, reference is madeto the accompanying drawings forming a part hereof,

Figure 1 is a partly sectional side view of Fig. 2 is an enlargedexterior side ,view of the entrance end of the machine, except that thefront bar forming a part of the frame thereof is removed. Fig. 3 isatopview of the same, except that certain parts shown in Fig. 2 are removed,and the 'ar removed in Fig. 2 restored. Fig. 4 is a section I of Fig. 3taken on the dotted line x.x. Fig. 5 is an enlarged exterior sideviewgof the central portion of the machine except that the front barforming a part of the frame is removed as in Fig. 2. Fig.6 is a topviewof the said parts of the machine with the'bar removed in Figs. 2 and5 restored. Fi 7 isan enlarged exterior side view of the ,de ivery endof the machine with the bar before referred to removed. Fig. 8 is a toview of the same with the said bar restore Fig. 9 is a View similar toFig. 6, except that a modified construction f pasting devices is i"illustrated; Fig. 10 is a end view of Fig. 9 A ,---looking in thedirection indicated by the arrow. I

Referring now to Figs. 1 to 8 incluslve, of

the drawings, the frameof the machine con- Y sists of the longitudirfaland transverse bars respectively denoted by 1 and 2. The frame issupported by a stand which to facilitate I the removal of the machinefrom place to placeis provided with two truck wheels on a transverseaxle 1). One of these Wheels is shown, and that is in Fig. 1 where it isrepre- 0 sented by d. 3 and 4. are respectively, the entrance and thedelivery runway for the cans,one of which cans isshown in Fig. 1andmarked X. 5, 5 are endless conveyer belts whereby the cans arecarried long1tud1- n5 nally of the machine in the labeling operaadjustedone with another as to admit of thetion, and the said belts are mountedon the pull s 7 and 9, the latter being considerably sma er in diameterthan the former, for a purpose hereinafter described. The shaft of thearger pulle s 7 which are situated at the entrance end 0 the machine, issupported in the standards 10, the lower ends of which rest and areadjustable in height in the sockets 12. This construction allows cans ofdifferent diameters to ass under and of their being carried forward bythe belts; and when the said standards are adjusted in height they arefastened by means of the set screws e. 14 is the receptacle for cementwhich is li uefied by heat, and 15 15 are wheels Whidli are rotated inthe cement receptacle by means of any suitable devices to apply cementto the bodies of cans as they are carried forward and over the saidwheels by the conveyer belts 5. The cement receptacle is held in placeby bolts f which depend from the forward transverse bar 2 of the frame,and pass through slots in extensions 16 of the said rece tacle, asbestshown in Figs. 2 and 3, whereby the receptacle is made adjustable inposition. 17 is a fixed plate so.

orted by the longitudinal bars 1 of t e rame, having rails g whichextend over the cement receptacle 14 and upon which the flanges of theheads of the cans roll.

By reference to Figs. 3 and 4, it will be seen that the rails g arelaced exteriorly of the cement wheels, an that between the said wheelsare situated two supplemental rails .h which are fastened to the rearend of the cement receptacle, and elevated slightly above the rails g,as shown in- Fi 4. By this construction the cans imme iatel beforereachin the cement Wheels are llfted from the rai s g by thesupplemental rails .h, and after passing from them, roll on to the.

plate 17. The sup lemental rails h are set so as to be practical y on alevel with the top of the cement wheels, consequently the same amount ofcement is invariabl applied to the can bodies, which effect wou d not bethe case should the cans at the time of the application thereto of thecement,-b'e supported by the flanges of the heads, for the reason thatthe flanges of cans vary in thickness or projection beyond the bodies.19 is the spriu -held table upon which a stack of labels are placed, andby which the upper label is always held slightly below the surface of alabel guide hereinafter described. 20 is the label guide before referredto, consisting of fixed rails t which are supported from thelongitudinal bars 1 of the frame by means of the rods j, and thelongitudinally adjustable rails is. These adjustable rails are seated indepressions (see Fig. 5) in the fixed rails 71 with their forward endscovered b the projections m of the fixed rails, in or er that at alltimes there is preserved a continuity of surface upon which the cansroll. 21 is a stretcher wire extendin across the adjustable portion ofthe labe guide to which its ends are fastened, from under which the rearend of the upper label is drawn by the rollin can.

eferring to Fig. 5, y is an edge on the fixed bars 1' of the label guidewhich in all cases is in vertical alinement with the forward edge of thestack of labels, and this edge must always bear a certain relation tothe vertical center line of the cement wheels 15. For instance, in theaffixing of labels to the largest cans, the distance between these twopoints will be practically the circumference of the can, in order thatthe portion of the can to which cement has been applied will roll over,and pick up the forward end of the top label of the stack, and thecement receptacle is therefore adjusted in position to effect thatresult. When cans of smaller diameter are to be labeled, the saiddistance must be a multi le of the circumference of the cans thus: f acan to be labeled has a circumference which is onehalf that of thelargest can, it would be practically impossible to decrease the distancebetween the said points one-half, consequently the said receptacle wouldbe kept in its original position, and the cans would merely make tworotations before reaching the point y. But should the original distancenot be a multiple of the circumference of the smaller cans, the cementrece tacle would have to be moved longitudina y of the machine to such adistance that a certain number of rotations of the can, the cementedortion of the can will come into con tact with and pick u the forwardend of the label; It must be orne in mind that the upper label of thestack of labels is flush with t e top edge of the longitudinal bars 1,and

by reference to Fig. 5 of the drawing, it will be seen that the edge yof the label guide is below the label, and from near that point, theguide rises to a height which is above the said rails, and thisincreased height is maintained until the can is about to come intocontact with and press upon the pasting belt 24. The object of thisconstruction is tomake the can during the labeling1 opera tion, traversea reater distance t an the length of the labeF the end of which is drawnfrom under the wire 21, thus placing sufficient tension on the label tocause it to be wrapped tightly around the can. 22 is a paste potsupported by one of the longitudinal bars 1 of the frame along which itis adapted to be slid, and the means for its attachment to the said baris of such character as to admit of the adjustment of the paste pot withrespect to the adjustable portion of the label guide and particularl tothe wire 21. 24 is an endless pasting elt which is carried by a Wheel 18in the aste pot, and a sheave 25 which is tight on t e shaft 27 (see 75Fig. 6) but which is moved longitudinally of the said shaft when thepaste pot is adjusted, and thereby brought into alinement with thepastewheel.

B reference to the ibwer lay of the pasting belt which applies paste tothe label, enters the paste pot near its bottom, and in consequence, verthin paste cannot be used, as it would leak from the pot. supported byinclined bars 31 ada ted to slide in bosses n formed on the stan ards 33which support the shaft 34 of the smalle. pulleys 9 v whichtogether'with the larger,

pulleys 7, before referred to, carry the conve er belts 5. The object inmaking the u leys 9 smaller in diameter than the puleys 7, is to providefor the labeling of cans of various diameters, without verticaladjustment of the standards 33. The conveyer belts at the delivery endof the machine when slightly deflected in a downward direction bypressure thereon of the tension ulleys 30 have such height above thecushloned bed 35 as to exert the desired (pressure on the labels of cansof the largest ameter being labeled. Owing to the inclined osition ofthe bars 31, and their longitu inal adjustability, a forward movement ofthe said bars lowers the'tension pulleys 30and the lower lay of theconveyer belts upon which they bear, and thereby causes them to bear onthe labels of cans of a smaller diameter. 37 is a roller arranged tobear with a yielding pressure on the lower lay of the block 40 placedloose y on the shaft 34 of the pulleys 9. 36 is a! gravity roller whichrests on the lower lay of the endless conveyer belts 5, at a pointdirectly over the forward or entrance end of the label table 19.

In the rapid passage of cans under the roller the same has imparted toit a vertical vibratory movement and practically strikes the belt overeach can at the time that its cemented portion comes into contact withthe forward end of thelabel, thus causing the label to adhere to the canmore fully than if the can were subjected merely to the weight of theroller.

I am aware that it is not new to apply tension rollers to belts, but inmy invention 13" Fig. 5 it will be seen that 80 30, 30 are tensionpulleys 85 situated in the. 0t and receives its rotation 1 from the saidbe t; and in order that the resceases is considerably greater than thatdue to the weight of the descending body.

4 The pasting belt is normally clear of the label, but is pressed downand brought into contact with it by the can. Depressions o I in theadjustable rails is of the label guide receive the pasting belt whenforced down by the, can, at the place where the ends of the labels'arelapped. In some cases it is desirable to use very thin paste and as suchwould leak from the aperture through which shown in Figs. 9 an 10 towhich referencethe lower lay of the pasting belt enters the paste pot, Iemplo the pasting devices should be made. In the said 'figures, the

i pasting belt 24 does not entervthe paste pot 22 but receives itscoating of paste from the' circumference of the rotary disk 41 which issure of the disk on the belt will be un orm notwithstanding variationsin the thickness of the belt, the paste pot ispivoted by m'eans iofflbolts to In s 42 between the brackets 43 which carry t e shaft 45 ofthe pasting .belt Wheel '47, and is spring-held. The spring mechanismwhich I preferably use to yieldingly sustain the paste pot, consists of'a spring 49fastened to the pot, 'a rigid bar 50 i I ing ad ustments aremade.

The tension pulleys30 are thenadjusted so that the lower lay of the coni 5 veyer'belts will bearproperly on the cans to belabeled, and the roller 37 moved forward so asto press down the belt on the'can immediately before the can reaches thepasting -belt."- The cement rece tacle is now-moved fc its cement wheelsand the edgev y of the to aposit onwhereint e distance between fixedrails of the label guide will be amultile of. the circumference of thecans. The abel table is-then provided with a stack of labels of therequired length which are rear end of the label tobe applied to the can,

and which is susceptible to adjustment with respect to the cementapplying devices, and a paste-applying mechanism which is adjustable inposition with respect to the movable section of the label guide,combined with a vertically adjustable conveyer belt,
